Description

Technical background

The The present invention relates to the construction of a device for Eliminate static charge that is designed to be static Charge caused problems can effectively prevent.

previous State of the art

If non-conductive substances, such. B. Celluloid Articles, Plastic Articles, Glass, carpeting, etc. come in frictional contact with other substances, then can she a little piece Put on paper, dirt or the like. Even when taking off garments from chemical fibers, z. B. sweaters and the like can at dry air in the winter may be heard discharge noise or may in particular underwear cause a tingling sensation.

Increases after driving out of the vehicle and then touch your feet standing the ground, the vehicle body, so you can also here feel a slight tingling in the finger, and at the same time can for example, when the car radio is turned on noise may be heard (electric shock and RF interference).

To be triggered these phenomena are due to the fact that a non-conductive substance due is electrostatically charged by friction. One speaks then of electrostatic charge of an object. To an electrostatic Charge occurs when an electron of an object, that is in the outermost orbit of an atom of its substance and moved in it, brought to it will be different from its original one To remove orbit and move to another substance.

The Contains atom a number of electrons moving around the nucleus. Since in the normal state, the number of electrons is equal to the number is the proton of the nucleus, the substance normally remains in a neutral, electrically balanced state.

going however, some of the electrons are due to frictional contact lost to the atom, so in the substance on the one hand decreases negative charge by the amount of charge, the number of lost On the other hand, the positive electrons increase Charge its protons around the opposite amount of charge, which corresponds to the number of lost electrons. Consequently the entire substance is positively charged. For the other stuff on the other hand, which comes in frictional contact with the non-conductive substance was, increased the negative charge, because the excess amount of electrons passes him, making it complete charged with negative electric charge.

Reach Two types of fabrics in frictional contact, which becomes one type of fabric positively charged due to electron loss, while the other type of substance negative due to an excessive increase in the number of electrons is charged. Whether a substance is negative and another substance positively charged, must by combining two types of fabric be found out. Are two types of fabrics together rubbed, the one substance is positive and the other charged negatively.

The Occurrence of such electrostatic phenomenon is limited not only on non-conductive substances. Electrically conductive substances be alike charged by friction, except that in them charges (amounts of electrostatic Charge) quickly to a side with lower potential can be. Consequently, such a phenomenon as described above, with electrically conductive substances not to watch. On the other hand, non-conductive substances a high resistance value, so that a current flow (charge) in a non-conductive substance is unlikely. Is accordingly Once a substance has been charged, the charge remains for a long time Time in one place and then one speaks of an electrostatic Charging.

The Fact that in a season like winter, when the air is dry, more often to electrostatic charge comes as in wetter seasons, is justified by That charges in winter because of the lower water content of Air is not so much passed on to the earth.

A vehicle is isolated from the road surface by its tires. Electrostatic charge arises here by the friction between the vehicle body and the air while driving. A vehicle occupant seated on a seat is electrified by frictional contact with the seat due to vibration emotionally charged. In addition, vehicles are recently equipped with a lot of electronics and thus the vehicle body may be exposed to floating electrostatic charges.

There the charges to be discharged from the supercharged vehicle body via a have very high potential, they will even discharge with a crackling sound when the person is stands on the ground and comes with a finger near the vehicle body. In general, the amount of energy is then so low that the discharge finished in no time. For this reason, by the discharge of the Electrostatic charge did not cause such electric shock as big as common with electricity, and the person feels at best a kind of tingling sensation. For However, some people, such an electric shock is extremely unpleasant.

at Tanker or similar Vehicles carrying fuel However, it must be assumed that it is due to electrostatic Discharge in the tank can unexpectedly lead to accidents, so take care of it will that discharge over a falling on the road surface and so a connection with the Earth making chain always done to earth. Many car drivers meet similar Take precautions by using electrically conductive rubber material.

a Electric shock caused by electrostatic charging you do not just have to suffer from vehicles as described above, even when touching a door handle in the hotel it can come to it.

At the Go across a concrete floor, wood, waxed tiles, carpeting, a dirty doormat or electrically conductive tiles and the like, the body produces a Person due to electrostatic charge charge with an extraordinary high potential. Electrostatically so charged, the body of the Person therefore unwanted Have effects on other objects. Examples are z. B. in IS and LSI systems to observe.

So far For example, people working in these areas have something called grounding for persons Also called anti-static wristband, applied to electrostatic Charging particularly sensitive components from the risk of destruction by from the human body to protect generated electrostatic charge. This could the from the human body be safely discharged to the earth. This anti-static wristband in other words, that the potential at the hand or on the fingers opposite electrical and electronic components are thereby lowered to zero, that the person's skin is grounded to cause unwanted effects on the person machining electrical and electronic components to prevent.

What The relationship between electrostatic charge and human concerns, so occur As described above, two kinds of problems. For one thing, the Human electrostatic charge through a charge-giving object exposed and on the other hand, a charge-giving object by influenced by humans.

to Time can be that described above, by electrostatic However, charging caused problems through the use of grounding either from the side of the object or the person prevent.

Yet it should be noted that certain problems persist, for example, the problem that the grounding, the on the vehicle use a fixed chain or an electrically conductive rubber strap, not as effective as caused by the electrostatic charge Prevent problems since they are made due to the fact that the road surface is generally off Concrete, asphalt or the like, and such groundings are heavy with the road surface come into contact, and for other reasons, only the effect can mitigate.

If the anti-static wrist strap is worn in IS and LSI systems, It can provide effective protection against the effects of electrostatic Provide charging as long as the body the person is securely connected to the earth wire on the ground side is. However, the problem here is that of constantly having one Wire man connected to the earth in his freedom of movement limited is. In addition, many have in the youngest Time projected building about any ground terminals in sockets, like that. that such groundings are not universal usable means for preventing electrostatic charging are suitable.

In recently, Time is also the problems caused by static charge often in office equipment, z. As in personal computers and the like, in the electrostatic Charging using medical-therapeutic devices and various types of electrical and electronic equipment such as electronic stoves etc. to observe. So heard For example, the prevention by electrostatic charging triggered disorders and accidents for general electrical appliances to the still not solved Problems.

Known was already that caused by electrostatic charge problems may be due to electrical and electronic equipment, that fluctuations in the amount of charge delivered to the device an unfavorable Influence on the performance of the device to have. The fact is, however, that it is difficult to take action to prevent the caused by electrostatic charge To take problems, because in the electrostatic charge it is a natural phenomenon, that can not be predicted.

• (1) Geeignete Maßnahmen zur Beseitigung elektrostatischer Aufladung wären zwar durch ein Verbinden des Gerätes mit der Erde möglich, die Erdung verringert aber die therapeutische Wirkung des Gerätes, da eine ausreichend hohe Stärke eines elektrischen Ionenfelds nur schwer erreicht werden kann. Hinzu kommt, dass sich bei einer Verbindung des Gerätes mit der Erde ein Erdschlussunterbrecher einschaltet, wodurch es eigentlich unmöglich wird, das therapeutische Gerät mit der Erde zu verbinden.
• (2) An einigen Aufstellorten lässt sich das therapeutische Gerät nicht mit der Erde verbinden.

Electrical devices, such as static-type medical therapeutic devices, that use very high potential (eg, 12 kV) are particularly risky in their application, since no suitable measures are taken to address the problems of electrostatic shock exposure to encounter. The reasons why the electrical equipment is used in this form can be illustrated as follows:

• (1) Although suitable measures to eliminate electrostatic charge would be possible by connecting the device to the ground, the grounding reduces the therapeutic effect of the device, since a sufficiently high strength of an electric ion field is difficult to achieve. In addition, when the device is grounded, a ground fault circuit breaker will turn on, making it virtually impossible to connect the therapeutic device to ground.
• (2) In some locations, the therapeutic device can not be connected to the ground.

The The present invention provides a solution to that of the conventional ones Means for preventing electrostatic charging occurring Problems and a way out of the difficulties described above Location where no means of preventing electrostatic charge is present, because the object of the present invention consists to provide a device for eliminating static charge, which ensures that the human and the charge-giving object or the charge-giving object itself no problems caused by electrostatic charging is suspended and a person during operation even then not limited in their freedom of movement when the device located right next to the person.

WO-A-92/20201 discloses a device for eliminating static charge the electrically conductive body contact for the feed electrostatic charge, a capacitor, a needle electrode and a Air ionization mechanism for the induction the discharge are used.

disclosure the invention

The The present invention relates to a device for eliminating static A charge according to claim 1.

Either one of the discharge devices or the exothermic devices or both together be embedded in a granite mixture and thus form a charge-absorbing Component similar a wire to be connected to the earth.

The Discharge devices can be designed so that they due to the electrostatic charge trigger a corona discharge.

With their structure provides the device according to the invention for removal static charge the features described below.

The apparatus of the present invention having the above-described structure can be securely held by the electrostatic charge supplying device as part of the static eliminating apparatus with a charge-giving object, e.g. As a person, a vehicle body, a door handle, an electrical device and the like are electrically connected. The electrostatic charges of the high voltage charged object are respectively supplied to and discharged from the discharge devices and the exothermic devices of the electrostatic discharge eliminating device from the discharge devices and exothermic devices via the electrostatic charge supplying device. At the same time, the charges are consumed as Joule heat and effectively reduced to a lower potential and eventually eliminated. In a paired arrangement of the electrical exothermic device and the discharge devices, the Joule heat generated at the time of discharge may heat the discharge devices and the ambient temperature around them to an appropriate temperature.

When Consequence of it can ionic charges in the air or in a medium at the time move the discharge more actively and thereby the discharge process more effectively simplify and release the charges introduced to the object more quickly. The charges are thus neutralized and the charge potential more effective reduced.

In the cases described the charge potential of the charged object varies with the amount of charge. Accordingly, you can the discharge devices and the exothermic device electrostatic charge for a wide range of high potential charges to effectively eliminate up to a low potential when the discharge devices and the exothermic devices accordingly the size of the capacities and the exothermic performance of the dischargers and exotherms Compose facilities from a variety of groups.

moreover are the discharge devices and the exothermic devices in the examples described above, for. B. in a granite mixture embedded, thereby enabling them to become electrostatic Charges similar like absorbing a wire connected to the earth. With help this construction can electrostatic charges due to the discharge and the exothermic Process more effectively discharged and neutralized, resulting in reduce the static charge of the charged object more easily leaves.

In the above cases, the exothermic devices include, for example, a heating element wire, z. A Nichrome ^™ wire, which has a high resistance to charge and is capable of readily consuming the electric field current as Joule heat. When such a coil wire wound around a coil wire is used, it is possible to increase the discharge power and the consumption of the electrostatic current, whereby the electrostatic charge can be reduced to an even greater extent.

Belongs in the examples described above, a discharge electrode to the discharge devices, the z. B. is capable of inducing a corona discharge, then electrostatic charge can be effectively discharged. In addition, when the discharge electrode is composed of a spherical electrode and a sleeve-like electrode, thereby forming the spherical electrode of a metal sphere, e.g. As iron, copper or the like and is arranged so that it electrically and mechanically comes into contact with a heating element wire which is wound around a spool as Nichrome ^TM wire, and the sleeve-like electrode of a metal sleeve, for. Stainless steel, has a certain discharge path and is arranged to surround the spherical electrode, and in addition, when an electrostatic charge absorbing substance capable of generating electrostatic charge is similar to that in the wire to be connected to the ground in the form of a granite filler around the heating element and the discharge electrode, then the electrostatic charge in the discharge process can be discharged and neutralized more effectively and more effectively reduce the electrostatic charge of the charged object.

consequently let yourself with the aid of the present invention, without the device for eliminating static charge itself is connected to the earth, achieve an equally high effect on the connection with the earth, as would the device is connected directly to the earth.

If For example, the device for removing static charge Consequently, it should not be borne by a person impairment the person's freedom of movement results, and the person can to move freely in their work.

Even then when the device for eliminating static charge in electrical and electronic devices is used, which has always been a problem has, if such a device was used the problems of static charge can be prevented without the device actually must be connected to the earth. Consequently, with the help of Device according to the invention To eliminate static charge prevents a breaker fails. She can rather than extraordinary effective means used to prevent electrostatic charge become.

With reference to the 2 In particular, the construction of the discharge circuit for eliminating the static charges according to the first embodiment will now be described.

In the drawing, 13 denotes a power source, z. B. a rechargeable battery for GS 7.2 (V). To a (+) pole of the battery 13 is a power supply line 15 via the on-off switch 4 for power supply, resistor R1 (300 o) and resistor R2 (1 kÙ) connected. To a (-) - pole b of the battery 13 is a ground line 16 connected via resistor R8 (300 O), resistor R7 (1 kÙ) and resistor R6 (1 kÙ).

At the top of the ground 16 is the socket 3 connected to the grounding plug. On the length of the ground line 16 are the Halteerdelektrodenplatten 7 and 8th and a third unloading assembly 60 connected without a second connection, as described below.

Between the power supply line 15 and the earth line 16 are a first charge removal assembly 20 and a second charge removal assembly 40 arranged parallel to each other and connected to each other.

As in 3 and 4 is shown in detail, belongs to the first unloading assembly 20 a housing 21 made of an electrically non-conductive synthetic resin with a lid 22 is provided. In the case 21 are a first heating element 23 and a first discharge electrode 26 arranged. The first heating element 23 consists of a core 23a made of acrylic resin and a winding 23b made of Nichrome ^TM wire, with which the acrylic core 23a is wrapped. To the first discharge electrode 26 include an iron ball 26a , which acts as a first counter electrode, and a stainless steel sleeve 26b in cylindrical form, the bottom of which acts as a second counter electrode on the iron sphere 26b each made of acrylic resin spacers 27 . 27 : .., sitting up. The first discharge electrode 26 is arranged so that the iron ball 26a with the Nichrome ^™ wire winding 23b got in contact. In addition, the acrylic case 21 with a certain volume of pumice granules 30 and granite blends 31 . 31 filled, leaving the first heating element 23 and the first discharge electrode 26 are embedded in them. In such an arrangement as described herein, the first discharge electrode is used 26 as a corona discharge electrode, through which the earth wire 16 and the Nichrome ^™ wire winding 23b supplied electrostatic voltage of the corona discharge in radial directions from the iron sphere 26a to the stainless steel sleeve 26b is suspended.

The first heating element 23 has at its top and bottom each an insulating plate 29a and 29b both made of an acrylic resin and the heating element on the right and left sides of the box-like housing 21 enclose. The upper insulating plate 29a has a groove 28 with a certain width, which is incorporated in a lying opposite the right and left side of the housing middle area. The iron ball 26a the first discharge electrode 26 is arranged so that its sleeve facing the open projecting surface with the incorporated groove 28 comes into contact, where at the iron ball 26a with the Nichrome ^™ wire winding 23b of the first heating element 23 can come into contact. By this arrangement, electrostatic voltage from the ground line 16 via the Nichrome ^TM wire winding 23b and created by the Nichrome ^TM wire winding 23b Heat are transferred. By means of the Nichrome ^TM wire winding 23b of the first heating element 23 can generate a certain amount of electrostatic voltage across the ground 16 was fed, discharged and an electrostatic current are consumed by being converted into Joule heat. It may also have the effect of neutralizing during the transfer of discharge charges by increasing the temperature of the iron sphere 26a the first discharge electrode 26 and the ambient temperature of the iron sphere 26a while improving the performance of neutralization by means of discharge.

The pumice granules 30 is in a middle area in a pumice layer 30 arranged with a width that is about a diameter of the iron sphere 26a equivalent. On the other hand, the granite mixtures 31 as a granite mixture layer 31 and 31 on both sides of the pumice layer 30 filled. Thus, a combination of pumice layer and granite blend layer may provide a discharge mechanism which, together with the heating element 23 , which performs the role of magma, has a high performance in the absorption of electrostatic charges and which is similar to that of the soil.

The stainless steel sleeve 26b the first discharge electrode 26 is with a connection on the ground wire side of a fourth charge removal assembly 70 via a charge residue discharge wire 71 connected, as will be described below. On the other hand, a (+) terminal of the Nichrome ^™ wire winding 23b of the first heating element 23 via the resistor R9 (10 kO), an electrically conductive, acting as a positive or negative left or right side counter electrode plate 32 made of stainless steel and the resistor R4 (1 kÙ) with the power supply cable 15 while one (-) terminal thereof through the resistor R10 (1 kO), an electrically conductive plate acting as the other of the positive and negative left or right side counter electrodes 33 made of stainless steel with the earth wire 16 connected is. Thus, the first discharge electrode 26 between the electrically conductive plates 32 and 33 which act as positive and negative, left-sided and right-sided counterelectrodes, respectively, wherein the positive and negative discharges are effectively combined to effect high-efficiency corona discharges.

Consequently, the charge voltage becomes high (for example, -7000 V to -10 000 V) and that of the ground line 16 over each of the holding earth electrode plates 7 and 8th each serving as a connection to the human as the object giving off charge, and via the chain 10 by a sufficiently strong corona discharge between the electrically conductive plates 32 and 33 , which act as negative or positive, left- or right-sided counter electrodes, reduced to a sufficiently low level. Thereafter, the charge voltage becomes both ends of the Nichrome ^™ wire winding 23b of the heating element 23 supplied, wherein to a certain degree a discharge takes place. Further, in the Nichrome ^™ wire winding 23b flowing electricity consumed in a very short period of time as Joule's heat, being rapidly reduced by corona discharge between the iron sphere 23a the first discharge electrode 26 and the sleeve 26b is brought about.

On the other hand, according to the drawings, the fourth charge elimination assembly 70 designed so that an LED 14 parallel to a first arrester 17 is arranged with the construction of a gas-filled Harrison discharge tube and that its (+) - side via the resistor R13 (100 kO) to the power supply line 15 and its (-) side over the charge residue discharge wire 71 with the stainless steel sleeve 26b the first discharge electrode 26 the first charge removal assembly 20 connected is. The cargo debris discharge wire 71 is via the resistor R3 (100 kÙ) with the earth wire 16 connected.

The charge residues (charges with which the sleeve is charged), that of the first discharge electrode 26 can not be discharged, thus practically by the LED 14 and the first arrester 17 over the cargo debris discharge wire 71 unloaded and eliminated.

Furthermore, the second arrester 47 between the connecting wires 44 and 49 connected. The discharge plate 46 is in the same way as described above, via a third arrester 18 which has the structure of a Harrison discharge tube and is filled with gases, with the earth line 16 connected. To the third arrester 18 is the short-circuit switch 5 the line for the electric field connected in parallel.

By means of such an arrangement as described above, the charge voltage (e.g., -7000 V to -10 000 V) passing across each of the hold earth electrode plates 7 . 8th and the chain 10 as a link for connecting the object giving the charge to the body of a person on the ground line 16 created and fed to her, the third arrester 18 supplied and discharged by this, so as to reduce the voltage. Furthermore, the residual stress also becomes on the discharge plate 46 laid out, which consists of a large copper plate, and discharged in a room in the housing. At the same time, the charge voltage at the second discharge electrode becomes 43 created, consisting of the positive and the negative counter electrode plate 43a and 43b consists of a corona discharge between the positive counterelectrode plate 43a and the negative counter electrode plate 43b effect, whereby neutralizes positive and negative ions and the electrostatic voltage is reduced. In addition, the negative counter electrode plate 43b the second discharge electrode 43 via the resistor R12 to the (-) terminal of the Nichrome ^TM wire winding 48b of the second heating element 48 and the positive counter electrode plate 43a with the (+) terminal of the Nichrome ^™ wire winding 48b of the second heating element 48 connected. Between the two connecting wires is the second arrester 47 connected. With this arrangement, the charge residues coming from the second discharge electrode 43 were not discharged through the second arrester 47 unloaded and reduced and in the area of the Nichrome ^TM wire winding 48b of the second heating element 48 further discharged and consumed in the form of Joulescher heat, so that the charge is reduced to a sufficiently low level.

test Examples

Based Experiments will now determine which effects the static charge eliminator according to embodiments of the present invention Invention on the absorption of static charge.

(Experimental Method)

In this experiment were accordingly 11 two Leyden bottles 75 and 75 on insulating boards 77 and 77 placed between the bottles and insulating plates each glass plates 76 and 76 were. On an insulating plate 81 became two glass columns 80 and 80 arranged on a housing 1 of the static charge eliminator according to these embodiments of the present invention, so that it was high above the ground. The Leyden bottles 75 and 75 were each charged to a potential of up to (7000V) by a Vande Graaff generator, and a grounding receptacle 3 The charge eliminator for static charge according to this embodiment was connected via a ground line for 10 A with electrodes 78 and 78 the respective Leyden bottles 75 and 75 connected, whereby the accumulated charges with a potential of (-) 7 000 V within the Leyden bottles 75 and 75 were unloaded. With an electrometer 79 were the potentials of the electrodes 15 Each time for 10 seconds, with a periodic reduction in the electrode potential was determined (experiment a).

On the other hand, each of the sufferers became bottles 75 and 75 charged to (-) 7 000 V and then again Spontaneous discharging without being connected to the static eliminating apparatus according to this embodiment, a periodic change in the potential of the electrode was measured 15 times for 10 seconds each, as in the experiment a (Experiment b).

The measurement results of experiments a and b are shown in a diagram in 12 shown.

As from the measurement results decreased when the device for eliminating static charge according to this embodiment was used (in experiment a), the period leading to the reduction of the original one Electrostatic potential to half is needed, from 91 seconds 22 seconds compared to if no removal device static charge and the electrostatic potential spontaneously discharged (experiment b). Based on the results was found that the discharge power by connecting the Device according to the invention to eliminate static charge is achieved, compared to spontaneous discharge is improved more than fourfold.

at a potential of only (-) 3 000 V to (-) 3 500 V it generally comes to no discharge and the human body also suffers no electric shock. Accordingly, it can be stated that the charge removal device according to the invention for static Charge in their performance actually is sufficient.

Furthermore, the above measurement results are supported by the curves (a) and (b) of 13 in which the damping factors of the electrostatic voltage in the experiments a and b are shown and compared with each other (a = damping factor 0.015 and b = damping factor 0.006) that the discharge power of the charge eliminator according to the invention for static charge is high.

14 shows the results recorded with a pen in the event that the Leyden bottles 75 and 75 were charged to a potential of (-) 5,000V in substantially the same manner as in the experimental procedure described above. From a comparison of the data, it can be seen that the effect on the static charge absorption is remarkably high when a static eliminating charge eliminating apparatus according to the embodiment of the present invention is used.

It should be noted, however, that, although according to the experimental method described above, the earth line 10A is connected only after the Leyden bottles 75 and 75 each were charged to a potential of (-) 7 000 V, it is also possible the Leyden bottles 75 and 75 charge when the ground line 10A with the electrodes 78 and 78 the Leyden bottles 75 and 75 was connected from the beginning, namely, if an on-off switch 4 is switched off for the power supply of the device for eliminating static charge. Then, the same experiment as described above can be easily repeated merely by turning on the on-off switch 4 is switched on after the charging has finished.

(Example 2)

The 15 to 18 show a device for eliminating static charge according to an embodiment of the present invention, the z. B. is designed as a vehicle-mounted charge eliminator for static charge.

15 illustrates the construction of a box-like housing part 90 the charge eliminator for static charge to be mounted in the vehicle. From the drawing shows that the housing 90 with mounting edges 91 and 92 is provided, which allow the device in the trunk to the body of a vehicle, as in 17 shown to fasten. On one side of the housing are a. Connector (connector for a cable set), which is designed as a Vierpolsteckvorrichtung, a short-circuit switch of the line of the electric field 5 and an LED 14 , each projecting out of the housing.

Within the housing part, various electrical and electronic components and wiring means are housed in a suitable arrangement, which includes a discharge circuit for eliminating the static charges, such as in 16 is shown form.

Out 16 It will be understood that the discharge circuit for eliminating the static charges has the same basic structure as the circuit according to the first embodiment of the present invention according to 2 and that a circuit for the power supply to a certain extent, however, constructed differently, since the vehicle from a battery 98 powered by (+) 12V.

In other words, in this embodiment, via a battery power supply 13 a current with a nominal voltage of (+) 7.2 V is supplied, which can be charged by means of the in-vehicle battery and a DC-DC converter with a battery terminal on the side surface of the connecting part 93 and connected to the power terminals + a and -b at the side surface of the static electricity eliminating circuit. Between the DC-DC converter 96 and the connector 93 are a timer acting as a switch 95 and a change-over relay that turns ON or OFF the timer.

The DC-DC converter 96 lowers the input current ( 12V ) from the battery in the vehicle 98 on + 6V and leads him the battery power supply 13 and the input terminals for the + a and -b power supply of the static charge eliminating circuit. The changeover relay 94 In order to eliminate the static charges, the discharge circuit supplies the mains voltage (+ 6V) by connecting the vehicle battery 98 and the DC-DC converter 96 is made by the fact that the timer 95 from the moment there is an ignition key switch in the on state 97 the vehicle is turned OFF for one minute. This disconnects the power supply after one minute has elapsed when the timer switches off 95 off.

To eliminate the static charge, the ground line 16 the discharge circuit for eliminating static charge of a Erdungsklenime the connection part 93 led to the outside. According to the 17 and 18 becomes the extension part 16a each with an outer door handle 99 the doors 102 and 102 , a door lock cylinder 100 and a Bowden cable door opening mechanism 101 of the vehicle AM.

The static eliminating charge eliminator having the above-described structure can absorb or lower the potential as described below, e.g. B. when the vehicle body 103 during driving of the vehicle generates AM friction with the air and thereby charges on (-) 7 000 V to 10 000 V.

More specifically, when the vehicle AM is stopped, the ignition key (IG-SW) 97 usually brought from his on position to the off position.

When the ignition switch is switched off, the change-over relay switches 94 the timer 95 for a minute. This converts the DC-DC converter 96 the from the vehicle battery 98 supplied supply voltage of (12 V) in +6 V and passes them to the input terminals for the power supply + a and -b of the discharge circuit to eliminate the static charges.

As a result, the discharge circuit for discharging the static charges performs exactly the same function as that in FIG 2 A circuit according to the first embodiment of the present invention, wherein the charge potential by means of the first to fourth charge elimination assembly and as a result of the charge removal effect of the third arrester 18 is lowered very quickly to a level that is lower than the discharge potential in the areas of the outer door handle 99 , the door lock cylinder 100 and the Bowden cable door opening mechanism 101 that are most likely to inflict an electric shock on a person's body.

As a result, when the driver has turned the key to the OFF position, the door is opened 102 opens, from the vehicle AM rises and the door is standing on the ground 102 is touched, the static charge of the vehicle is already reduced so far that no discharge takes place and he suffers no unpleasant electric shock.

The timer 95 also shuts off automatically after the set time of one minute has expired and cuts off the power to the discharge circuit to eliminate the static charge from the vehicle battery 98 , This is an unnecessary power consumption of the vehicle battery 98 locked out.

(Construction of First Charge Removal Assembly 126)

The 23 and 24 illustrate the construction of the first charge eliminating assembly 126 ,

In the figures, the number indicates 126a a box-like housing made of an electrically non-conductive synthetic resin, which is provided with a lid (not shown). In the case 126a are a heating element 141 with a multiple structure, a first arrester 142 and a second arrester 143 each configured as a Harrison discharge tube filled with gases and capable of absorbing an electrostatic shock, a first discharge plate 144 from a round iron with a certain diameter and a certain length, a second discharge plate 145 housed in copper with a certain plate thickness and the like. The heating element 141 consists of windings of Nichrome ^TM wire 141f . 141f , ..., with which the cores made of acrylic resin 141 to 141e each in a variety wrapped by layers of different sizes. A corona discharge electrode is formed according to the figures by forming two pin electrodes 145a and 145b made of iron so on the second discharge plate 145 be attached to the first discharge plate 144 are directed. While one side of the second discharge plate 145 the corona discharge electrode with resistor R22 (30 kO), one side of the Nichrome ^™ wire winding 141f and the second charge removal line 132a is connected, the other side of the second discharge plate 145 with the first inner wire 137 connected in the object. Furthermore, the other side of the first discharge plate 144 on the one hand via the first arrester 142 with one side of the Nichrome ^™ wire winding and the other with the fourth inner wire 134 connected in the object. The second arrester 143 is via the resistor R21 (30 kO) and the resistor R22 (30 kÙ) with the second charge removal line 132a and the other side of the Nichrome ^™ wire winding 141f connected in a row.

With the aid of the arrangement described above, charge voltage (eg -7000 V to -10 000 V) coming from the charge elimination chain as a link for connecting the human body as the object delivering the charge via the connector socket 163 for the charge elimination chain to the charge removal line 132a created and this was fed to the first arrester 142 created and reduced by discharge. Thereafter, it is replaced by one of a resistor R21, a resistor R22 and the second arrester 143 existing DC circuit shared and consumed by discharge. In addition, the residual charge through the heating element 141 converted into heat and then consumed. It is then attached to the first and second discharge plate 144 and 145 and the pin electrodes 145a and 145a existing corona discharge electrode delivered. If the charge voltage is so high that it can not be reduced by the three measures just described, then the positive and negative ions are neutralized by applying a corona discharge between the first discharge plate 144 and the pin electrodes 145a and 145a the second discharge plate 145 is brought about and thereby the electrostatic voltage is lowered to a sufficiently low level.

(Construction of Second Charge Removal Assembly 127)

The 25 to 28 show the structure of the second charge elimination assembly in detail.

In the drawings is with 127b a box-like housing made of an electrically non-conductive resin called, with a lid 127a is provided. The housing 127b is through the first and the second each consisting of resin partition 148 and 149 each divided into a larger compartment and two smaller compartments.

On one side of the housing are in the middle of the larger compartment a rectangular electrode 146 made of copper and a spherical electrode 147 made of iron so that they face each other at a certain discharge distance and also in a layer of pumice granules and a granite mixture 31 are embedded.

To the copper electrode 146 is an input of the first charge removal line 131 connected. The iron electrode 147 is on one side with the third charge removal line 132 connected.

A spherical electrode 150 made of iron is mounted almost in the middle of the middle, smaller compartment. The iron electrode 150 is with one end of the fifth inner wire 135 connected within the object.

In the smaller compartment on the other side are a first and a second rod-shaped neon electrode 149a and 149b which are arranged to be coaxial with each other at a certain discharge distance.

The first neon electrode on one side 149a is essentially the same way with the fifth inner wire 135 inside the object connected like the iron electrode 150 on the other hand. The second neon electrode on the other side 149 is with both the iron electrode 150 on the other side and with a U-shaped Nichrome ^TM wire winding 160 as well as with the third charge removal line 132 via the Nichrome ^TM wire winding 160 connected.

In the structure just described, the electrostatic charge emitted by the object, that of the built-in connector 121 the electric field electrode or the connection socket 163 the charge elimination chain respectively via the first and the third charge removal line 131 and 132b to is guided, both to the copper electrode 146 as well as to the iron electrode 147 in any case, which causes the corona discharge between the electrodes 146 and 147 is effected and the ions produced with the help of pumice granules filled around them and the granite mixture 31 effectively absorbed and neutralized.

Furthermore, the one side of the smaller diameter iron electrode 150 and one side of the first neon electrode 149a connected to a body ground and thus the body via the fifth inside wire located in the object 135 connected to the earth. The other side of the smaller diameter iron electrode 150 and the other side of the first neon electrode 149a are sent to the Nichrome ^TM wire winding 160 connected and that of the third charge removal line 132 supplied electrostatic charge is applied. The electrostatic voltage is generated by the Nichrome ^TM wire winding 160 initially consumed as heat and then outward around the smaller diameter iron electrode 150 released around. At the same time, the corona discharge between the first and second neon electrode 149a and 149b triggered and then the charge eliminated.

(Construction of Third Discharge Assembly 128)

The 28 to 30 illustrate the construction of the third charge eliminator assembly 128 in detail.

In the drawings is with 128b a box-like housing made of an electrically non-conductive resin called, with a lid 128a is provided. In the case 128b are a heating element 151 , an arrester 152 , a discharge plate 153 made of copper with a certain plate thickness and one of two counter-electrode plates 154 and 156 existing discharge electrode, both of which are designed according to the figures each as a flat plate made of stainless steel housed. The heating element 151 consists of one with Nichrome ^TM wire 151b wrapped acrylic resin core. The arrester 152 is designed as a gas filled Harrison discharge tube that is capable of absorbing electrostatic shock. The discharge electrode is constructed so that the counter electrode plates 154 respectively. 156 with the help of spacers 155 made of synthetic resin are arranged one above the other at a certain distance. Furthermore, the counter electrode plate 154 of the discharge electrode via resistor R24 to one side of the Nichrome ^™ wire winding 151 and the counter electrode plate 156 through resistor R23 to the other side of the Nichrome ^™ wire winding 151 connected. The arrester 152 , which has the structure of a Harrison discharge tube and is filled with gases, becomes on both sides with the Nichrome ^™ wire winding 151b of the heating element 151 connected.

By means of such an arrangement as described above, the charge voltage (e.g., -7000 V to -10 000 V) applied to the fourth charge removal line 132 as a link for connection with the human body when the charge-emitting object was applied and supplied to the arrester 152 discharged and degraded by this and further from the heating element 151 consumed. Subsequently, the residual voltage across the resistor R23 to the large-area counterelectrode plate 156 applied, in turn, a corona discharge with the counter electrode plate 154 that over the counter electrode plate 156 is disposed, wherein the positive and negative ions are neutralized and the electrostatic voltage to be reduced is reduced to a sufficiently low level. A corona discharge occurs when the discharge plate 153 to the fifth inner wire 136 is connected within the object. In addition, the resistors R23 and R24 each have a resistance value of, for example, approximately 30 kO, and moreover have the effect of dividing the static charge into smaller segments and reducing the voltage. The discharge plate 153 is arranged so that it alone causes a discharge (usually on the side with a connection to the earth) when the static charge on the sixth inner wire 136 is supplied within the object. As a result, a sufficient amount of static charge is eliminated.

In the static electricity charge eliminating apparatus according to this embodiment, the two counter electrode plates are 154 and 156 each carried out particularly large area, which is easy to discharge (and dark discharge is possible). If the discharge gap between the two were reduced, then the electrostatic voltage would still be sufficiently low so that it can be determined that the device is suitable for a low electrostatic voltage.
